Therefore, the numerical values, shapes, materials, constituent elements, arrangement positions of constituent elements, connection forms, and the like shown in the following embodiments are merely examples and do not limit the present invention. Therefore, among the components in the following embodiments, components that are not described in independent claims that represent the highest concept of the present invention are described as arbitrary components.

  Each drawing is a schematic diagram, and is not necessarily strictly illustrated. In each of the drawings, substantially the same components are denoted by the same reference numerals, and redundant description will be omitted or simplified.

(Embodiment 1)
FIG. 1 is a diagram showing a lighting system 100 and lighting devices 10a, 10b, 10c, 10d, 10e, and 10f according to Embodiment 1, and is an example of a mesh network 20 configured by a plurality of lighting devices 10a to 10f. FIG.

  The lighting system 100 includes a plurality of lighting devices 10a to 10f having a communication function. In the lighting system 100, among the plurality of lighting devices 10a to 10f, adjacent lighting devices (for example, the lighting devices 10c and 10f) communicate with each other to establish a wireless communication path, thereby forming a mesh network. In addition, the lighting devices 10a to 10f can be connected for communication with a communication terminal 50 such as a tablet terminal.

  FIG. 2 is a diagram illustrating an example of the appearance of the lighting devices 10a to 10f. FIG. 3 is a block diagram illustrating a control configuration of the lighting devices 10a to 10f.

  The lighting devices 10a to 10f are, for example, ceiling lights as shown in FIG. 2 and are installed on building materials (such as ceilings) of buildings such as houses. Each of the lighting devices 10 a to 10 f includes a device main body 15 and a globe 16 that covers the device main body 15. The globe 16 is formed of a translucent resin material. The device main body 15 includes a light source 11, a device communication unit 12, and a device control unit 13, as shown in FIG.

  The light source 11 includes, for example, a plurality of light emitting diodes that emit white light, red light, green light, or blue light. The light source 11 is subjected to dimming control and / or toning control by the device control unit 13.

  The device communication unit 12 has an antenna and a wireless module. The device communication unit 12 wirelessly transmits and receives information on the lighting device different from itself and the operation of the lighting devices 10a to 10f. For example, the lighting device 10c can communicate with the lighting devices 10a, 10e, and 10f located next to each other. The device communication unit 12 of each of the lighting devices 10a to 10f can also communicate with the communication terminal 50. As a communication method, for example, a method of performing communication in a frequency band of a 2.4 GHz band such as Bluetooth (registered trademark) standardized by IEEE 802.15.1 is used.

  The device control unit 13 includes a CPU, a RAM, a ROM storing programs, and the like. In the present embodiment, the device control unit 13 has a mesh profile m1 and a user profile u1. The mesh profile m1 is a communication protocol used when a plurality of lighting devices 10a to 10f configuring the mesh network 20 and when the lighting devices 10a to 10f and the communication terminal 50 transmit or receive signals to and from each other. The user profile u1 is a communication protocol when the lighting devices 10a to 10f and the communication terminal 50 communicate with each other, and is a profile individually set by the communication terminal 50.

  The mesh profile m1 includes, as communication rules, addresses individually assigned to the lighting devices 10a to 10f, and authentication information such as a network encryption key. In the device control section 13, authentication information such as an address and an encryption key can be deleted or rewritten.

  Further, the mesh profile m1 includes commands for controlling the operation of the lighting devices 10a to 10f, such as dimming, toning, scenes, and schedules of the light source 11. Each of the lighting devices 10a to 10f operates according to a command originating from the communication terminal device 50 and transmitted via the communication path of the mesh network 20 in the mesh profile m1. For example, the lighting device 10a receives a command corresponding to the mesh profile m1 transmitted from the communication terminal device 50 in the device communication unit 12, and executes a command corresponding to the received mesh profile m1 in the device control unit 13. I do. At the same time, a command corresponding to the mesh profile m1 transmitted to itself is transmitted by the device communication unit 12 to the adjacent lighting devices 10b and 10c.

  The lighting devices 10a to 10f according to the present embodiment not only receive information using the communication path of the mesh network 20, but also transmit a command corresponding to the user profile u1 transmitted from the communication terminal 50 to the device communication unit. 12, the device control unit 13 executes a command corresponding to the received user profile u1.

  For example, the command corresponding to the user profile u1 includes a reset command that initializes the settings of the lighting devices 10a to 10f, respectively, and sets each of the lighting devices 10a to 10f to a state where the lighting devices 10a to 10f can participate in the mesh network 20. .

  On the other hand, the command corresponding to the mesh profile m1 does not include a reset command for initializing the settings of the lighting devices 10a to 10f and setting the lighting devices 10a to 10f in a state where the lighting devices 10a to 10f can participate in the mesh network 20. Therefore, the lighting devices 10a to 10f can be directly reset from the communication terminal 50 using the user profile u1, but are not reset indirectly using the mesh profile m1. This makes it difficult for the lighting devices 10a to 10f to be reset by mistake.

  FIG. 4 is a block diagram illustrating a control configuration of the communication terminal 50 communicating with the lighting devices 10a to 10f.

  The communication terminal 50 includes an operation unit 54, a display unit 51, a terminal communication unit 52, and a terminal control unit 53.

  The operation unit 54 is, for example, a touch panel for selecting or inputting a command for operating the lighting devices 10a to 10f. The display unit 51 is, for example, a liquid crystal monitor for displaying the individual operating states of the lighting devices 10a to 10f and for displaying the presence or absence of participation in the mesh network 20.

  The terminal communication unit 52 has an antenna and a wireless module. The terminal communication unit 52 is capable of communicating with the lighting devices 10a to 10f within a predetermined distance. As a communication method, for example, Bluetooth (registered trademark) is used. For example, communication is performed at a frequency different from the frequency used in the mesh network 20.

  The terminal control unit 53 includes a CPU, a RAM, a ROM, and the like. The terminal control unit 53 has a mesh profile m2 and a user profile u2. The mesh profile m2 has the same function as the mesh profile m1 of the lighting devices 10a to 10f, and the user profile u2 has the same function as the user profile u1 of the lighting devices 10a to 10f.

  The mesh profile m2 includes, as communication rules, addresses individually assigned to the lighting devices 10a to 10f, and authentication information such as a network encryption key. Authentication information such as an address and an encryption key can be input by the operation unit 54. The mesh profile m2 includes commands for controlling the operation of the lighting devices 10a to 10f, such as dimming, toning, scenes, and schedules of the light source 11. The communication terminal 50 can operate each of the lighting devices 10a to 10f based on a command of the mesh profile m2.

  The command corresponding to the user profile u2 includes a reset command for initializing the settings of the lighting devices 10a to 10f and setting the lighting devices 10a to 10f in a state where the lighting devices 10a to 10f can participate in the mesh network 20. On the other hand, the command corresponding to the mesh profile m2 does not include the reset command.

  Next, with reference to FIG. 5 and FIG. 6, a method of causing the lighting device 10f that has deviated from the mesh network 20 to participate in the mesh network 20 will be described.

  5A shows a state in which the lighting device 10f has not participated in the mesh network 20, FIG. 5B shows a state in which the lighting device 10f not participating in the mesh network 20 and the communication terminal 50 are communicating, and FIG. () Is a diagram showing a state in which the lighting device 10f has rejoined the mesh network 20. FIG. 6 is a flowchart in the case where a lighting device 10f not participating in the mesh network 20 is allowed to participate in the mesh network 20.

  As shown in FIG. 5A, the lighting device 10f of the plurality of lighting devices 10a to 10f is rejected from the mesh network 20 for some reason, for example, the encryption key is rewritten unintentionally, and the mesh device 20 does not participate. In some cases, the lighting device 10f does not constitute the network 20 (S1 in FIG. 6). In this case, the lighting device 10f attempts to join the mesh network 20 again, but since the lighting device 10f has already been removed from the mesh network 20, the mesh network 20 itself cannot recover the communication path.

  Therefore, as shown in FIG. 5B, the lighting device 10f is caused to participate in the mesh network 20 using the communication path of the communication terminal 50. First, a reset command corresponding to the user profile u1 is transmitted from the communication terminal 50 to the lighting device 10f. Thus, the lighting device 10f receives the reset command (S2 in FIG. 6).

  The lighting device 10f that has received the reset command sets the setting of its own lighting device 10f to a state where it can participate in the network (S3 in FIG. 6). Specifically, first, the current setting of the lighting device 10f is reset (initialized) (S31 in FIG. 6). By this reset, information on the operation of the lighting device 10f and authentication information such as an address and an encryption key stored in the device control unit 13 of the lighting device 10f are temporarily deleted.

  Next, association setting (participation setting in the mesh network 20) is performed for the reset lighting device 10f (S32 in FIG. 6). Specifically, the device communication unit 12 of the lighting device 10f transmits a beacon for notifying that the association setting is necessary to the outside. When a beacon is being transmitted, the lighting device 10f is in the full lighting state.

  The communication terminal 50 displays from the transmitted beacon that the lighting device 10f is requesting the association setting and acquires the UDID (Unique Device IDentifier) of the lighting device 10f. Thereafter, a predetermined operation is performed in the communication terminal 50, and the communication terminal 50 transmits authentication information (address, encryption key, and the like) for participating in the mesh network 20 to a command corresponding to the user profile u2. And transmits it to the lighting device 10f. This authentication information is associated with the UDID.

  In the lighting device 10f that has received the authentication information, the command corresponding to the user profile u1 is executed, and the authentication information such as the address and the encryption key is written in the device control unit 13. Thereby, the setting of the lighting device 10f is returned to the initial setting state, which is the same state as when originally participating in the mesh network 20. The lighting device 10f returned to the initial setting state stops transmitting beacons.

  Then, as shown in FIG. 5C, a communication path 20a is formed between the lighting device 10f and an adjacent lighting device 10c, and the lighting device 10f rejoins the mesh network 20 (see FIG. 5). 6 S4). The lighting device 10f participating in the mesh network 20 is operated and controlled using a command of the mesh profile m1.

  As described above, the lighting devices 10a to 10f according to the present embodiment include the device communication unit 12 that wirelessly transmits or receives information on the operation of the lighting devices 10a to 10f, and the plurality of lighting devices 10a to 10f that configure the mesh network 20. Each other, and the mesh profile m1, which is a communication protocol when the lighting devices 10a to 10f and the communication terminal 50 mutually transmit or receive information, and the mesh profile m1 when the lighting devices 10a to 10f and the communication terminal 50 communicate. A device control unit 13 having a communication protocol and a user profile u1 individually set to the communication terminal 50. The device control unit 13 is configured to execute a command corresponding to the mesh profile m1 received from a lighting device different from itself and a command corresponding to the user profile u1 received from the communication terminal device 50.

  According to this, when operating a predetermined lighting device (for example, the lighting device 10f), the predetermined lighting device (for example, the lighting devices 10a to 10e) is operated using the same mesh profile m1 as the other lighting devices (for example, the lighting devices 10a to 10e). It is possible to select whether to operate using the common user profile u1. Thereby, when performing wireless communication with the lighting devices 10a to 10f, an appropriate communication path can be selected as needed. Further, even if the lighting devices 10a to 10f are installed on the ceiling of a building or the temperature of the lighting devices 10a to 10f is high due to use, the lighting devices 10a to 10f can be returned to the initial setting state by wireless communication.

  In addition, the command corresponding to the mesh profile m1 does not include a reset command for initializing the settings of the lighting devices 10a to 10f and setting the lighting devices 10a to 10f in a state in which the lighting devices 10a to 10f can participate in the mesh network 20. The command corresponding to u1 may include a reset command.

  According to this, when resetting a predetermined lighting device (for example, lighting device 10f), other lighting devices (for example, lighting devices 10a to 10e) are not reset using the communication path of the mesh network 20. . As a result, it is less likely that other lighting devices will be reset by mistake.

  When the lighting device 10f becomes the lighting device 10f that does not configure the mesh network 20, the device control unit 13 uses the command corresponding to the user profile u1 to change the lighting device 10f that does not configure the mesh network 20 to the mesh network. 20.

  According to this, by using the communication terminal 50 having the user profile u2, the lighting device (for example, the lighting device 10f) deviating from the mesh network 20 is directly returned to the initial setting state, and is rejoined to the mesh network 20. Can be.

  The lighting system 100 according to the present embodiment includes a plurality of lighting devices 10a to 10f.

  According to this, when operating a predetermined lighting device (for example, the lighting device 10f) of the lighting system 100, the predetermined lighting device (for example, the lighting devices 10a to 10e) is operated using a mesh profile m1 common to other lighting devices (for example, the lighting devices 10a to 10e), or communication is performed. It is possible to select whether to operate using the user profile u1 common to the terminal 50. Thus, when performing wireless communication with the lighting devices 10a to 10f of the lighting system 100, an appropriate communication path can be selected as necessary.

(Embodiment 2)
The lighting devices 30a, 30b, 30c, 30d, 30e, and 30f according to Embodiment 2 are different from themselves using the communication path of the mesh network 20 without being directly given a command by the communication terminal 50. A command is given from the lighting equipment.

  Illumination system 100A according to Embodiment 2 includes a plurality of illumination devices 30a to 30f having a communication function (see FIG. 8A). In this lighting system 100A, among the plurality of lighting devices 30a to 30f, adjacent lighting devices (for example, the lighting devices 30b and 30d) communicate with each other to establish a wireless communication path and configure a mesh network. The lighting devices 30a to 30f can be connected to a communication terminal 50 such as a tablet terminal.

  FIG. 7 is a block diagram illustrating a control configuration of the lighting devices 30a to 30f.

  Each of the lighting devices 30a to 30f includes a light source 11, a device communication unit 12, and a device control unit 13.

  The device control unit 13 has a mesh profile m1a and a user profile u1. The mesh profile m1a is a communication protocol when the plurality of lighting devices 30a to 30f and the communication terminal 50 that constitute the mesh network 20 transmit or receive signals to and from each other. The user profile u1 is a communication protocol used when the lighting devices 30a to 30f and the communication terminal 50 communicate with each other, and is a profile individually set by the communication terminal 50.

  The mesh profile m1a includes, as communication protocols, addresses individually assigned to the lighting devices 30a to 30f, and authentication information such as a network encryption key.

  Further, the mesh profile m1a includes commands for controlling the operation of the lighting devices 30a to 30f, such as dimming, toning, scenes, and schedules of the light source 11. Each of the lighting devices 30a to 30f operates according to a command originating from the communication terminal device 50 and transmitted from the mesh profile 20 via a communication path of the mesh network 20.

  In the lighting devices 30a to 30f in the present embodiment, a command corresponding to the mesh profile m1a and a command corresponding to the user profile u1 each include a reset command for setting the settings of the lighting devices 30a to 30f to an initial setting state. Have been. Note that the initial setting state refers to the same setting state as when originally participating in the mesh network 20.

  The communication terminal 50 includes an operation unit 54, a display unit 51, a terminal communication unit 52, and a terminal control unit 53.

  The terminal control unit 53 has a mesh profile m2 and a user profile u2. The mesh profile m2 has the same function as the mesh profile m1a of the lighting devices 30a to 30f, and the user profile u2 has the same function as the user profile u1 of the lighting devices 30a to 30f. That is, the commands corresponding to the mesh profile m2 and the user profile u2 include the reset command for setting the settings of the lighting devices 30a to 30f to the initial setting state.

  The lighting devices 30a to 30f according to the present embodiment not only receive information using the communication path of the mesh network 20, but also send a command corresponding to the user profile u1 transmitted from the communication terminal 50 to the device communication unit 12. The device control unit 13 is configured to execute a command corresponding to the received user profile u1.

  However, in the present embodiment, not only the command corresponding to the user profile u1 but also the command corresponding to the mesh profile m1a includes a reset command for setting the settings of the lighting devices 30a to 30f to the initial setting state. Therefore, for example, it is possible to transmit a reset command to the nearby lighting device 30a and use the reset command of the mesh profile m1a to set the remote lighting device 30f to the initial setting state.

  Next, a method of resetting the lighting devices 30f participating in the mesh network 20 will be described with reference to FIG.

  8A shows a state in which a predetermined lighting device 30f is participating in the mesh network 20, FIG. 8B shows a state in which the lighting device 30f is reset using the communication path of the mesh network 20, and FIG. FIG. 9 is a diagram illustrating a relationship between the lighting device 30f and the mesh network 20 that have returned to the initial setting state.

  As illustrated in FIG. 8A, the lighting device 30f among the plurality of lighting devices 30a to 30f may perform an operation not intended by the user for some reason. The operation not intended by the user refers to, for example, a case where the light intensity and color of the lighting device 30a are different from those of the other lighting devices 30a to 30e. When the lighting device 30f is close to the communication terminal 50, the communication terminal 50 can be used to directly reset and return to the original position. However, when the lighting device 30f is far away, the communication terminal 50 can reach the position. Must be moved, which takes labor and time.

  Therefore, as shown in FIG. 8B, the lighting device 30f is reset to the initial setting state using the communication path by the mesh network 20. First, the communication terminal 50 transmits a reset command for the mesh profile m1a to the lighting device 30a. This reset command is transferred to the lighting device 30f via the lighting device 30a and the lighting device 30c that configure the mesh network 20. That is, the lighting device 30f receives the reset command of the mesh profile m1a via the lighting devices 30a and 30c different from itself.

  The lighting device 30f that has received the reset command sets the settings of its own lighting device 30f to the initial setting state. Specifically, the current settings (light control, color control, etc.) of the lighting device are set to the initial setting state. Note that the address and the encryption key in the device control unit 13 of the lighting device 30f are not erased and remain stored.

  As a result, the lighting device 30f that has been returned to the initial setting state is operation-controlled again using the command of the mesh profile m1a in the same manner as the other lighting devices 30a to 30e, as shown in FIG. You.

  In resetting the lighting device 30f, the address and the encryption key stored in the device control unit 13 may be deleted. Even when the address and the encryption key are erased, the association can be performed by exchanging the public key, and thereafter, the address and the encryption key can be added to return to the initial setting state. Further, similarly to S32 shown in FIG. 6 of the first embodiment, it is also possible to make an association setting for the lighting device 30f using the user profile u2 of the communication terminal 50.

  As described above, the lighting devices 30a to 30f according to the present embodiment include the device communication unit 12 that wirelessly transmits or receives information regarding the operation of the lighting devices 30a to 30f, and the plurality of lighting devices 30a to 30f that configure the mesh network 20. A mesh profile m1a, which is a communication protocol when the lighting devices 30a to 30f and the communication terminal 50 transmit or receive information to each other, and a case where the lighting devices 30a to 30f and the communication terminal 50 communicate with each other. And a device control unit 13 having a user profile u1 that is individually set in the communication terminal 50 according to the communication protocol. The device control unit 13 is configured to execute a command corresponding to the mesh profile m1a received from a lighting device different from itself and a command corresponding to the user profile u1 received from the communication terminal 50.

  According to this, when operating a predetermined lighting device (for example, the lighting device 30f), the predetermined lighting device (for example, the lighting devices 30a to 30e) is operated using the same mesh profile m1a as the other lighting devices (for example, the lighting devices 30a to 30e). It is possible to select whether to operate using the common user profile u1. Thereby, when performing wireless communication with the lighting devices 30a to 30f, it is possible to select an appropriate communication path as needed. Further, even if the lighting devices 30a to 30f are installed on the ceiling of a building or the temperature of the lighting devices 30a to 30f is high, the lighting devices 30a to 30f can be returned to the initial setting state by wireless communication.

  Further, the command corresponding to the mesh profile m1a and the command corresponding to the user profile u1 may include a reset command for setting the settings of the lighting devices 30a to 30f to an initial setting state.

  According to this, not only the command corresponding to the user profile u1 but also the predetermined lighting device (for example, the lighting device 30f) can be reset using the command corresponding to the mesh profile m1a. Options can be increased.

  Alternatively, the device communication unit 12 may receive a reset command corresponding to the mesh profile m1a from a lighting device different from itself, and the device control unit 13 may execute the reset command corresponding to the mesh profile m1a.

  According to this, for example, a reset command is transmitted to the lighting device 30a, and the lighting device 30f at a remote position can be returned to the initial setting state using the reset command corresponding to the mesh profile m1a.

  Although FIG. 8 illustrates an example in which the lighting device 30f is returned to the initial setting state, the present embodiment is not limited to this. For example, when the lighting device 30a participating in the mesh network 20 does not match the dimming or toning with the other lighting devices 30b to 30f, the lighting device 30a is temporarily returned to the initial setting state. Can also be used.
